CURBING.

Application filed February My invention relates to sectional curbing forwalks, lawns and the like, and it has for its object to provide animproved curb of this class.

In constructing a curb for a lawnthe usual practiceheretotore has beento first dig a trench and erect therein a mold and then to fill the moldwith concrete or cement which was a laborious and comparativelyexpensive method. My invention provides ready made units consisting: ofa previously molded bar or rail and pedestal units which canbe quicklyand properly installed at very little expense by an unskilled workman.

In the accompanying drawings: F'gure 1 is a plan view of a section ofcurbing constructed in accordance with my invention.

Figure 2 is a section on line 2-2 of Figure 1.

Figure 3 is a section on line 38 of Figure 2.

Figure 4: is a perspective view of one of the bar or rail units of mynew curb.

Figure 5 illustrates the construction of the curb at a corner.

My new curb is constructed from two kinds of units, viz, pedestal units1, and bar or rail units 2.

Each rail or bar unit 2 is a molded block of concrete, cement or thelike formed with solid heads or end portions 3 connected by anintermediate or body portion 4 constituting the greater portion of itslength which 5 is recessed upon one side as at 5 so that said bodyportion is of angle-iron shape in cross section. This shape affords thenecessary strength and at the same time requires less material thanwould a solid rail or bar made rectangular in cross section. If desired,longitudinal reinforcing bars of metal may be incorporated in each railas is customary in strengthening bars, columns and other structures ofconcrete or cement. Each end 5 of the bar unit 2 is formed with avertical groove 6, for a purpose that will presently appear.

Each pedestal unit 1 is a molded block of concrete, cement or the like,formed with a flat top surface or shelf 7 at opposite sides of which areupstanding ears 8, 8, each having embedded therein a square metallic nut9 to receive a screw 10.

In constructing my new curb a shallow trench is made in the ground alongthe line the curb is to occupy and at regular interblocks of wood 11 arethen positioned be-.

tween the inner ends of the. screws 10 and the bar units 2. After theparts have been installed as described, it will be clear that when bothot the screws 10 of each pedestal arescrewed inward the opposed woodblocks 11, 11, are clamped against the opposite sides of the two bars 2resting on the pedestal and serve to bring the same into exact register.It will also be clear that by backing out one screw 10 and screwing inthe op posite, the two bar unit ends can be shifted bodily laterally onthe pelestal and that by recourse to this method of adjustment after allof the bars 2 are in place the latter can be brought into exactalinement, or positioned relatively, as desired.

At each pedestal 1 the vertical grooves 6 of the abutting ends oi thebar units 2 register and provide a chamber, Figures 1 and 3, to receivea key filling 12 of cement, concrete or the like. In the preferred formof my invention the body portion of each pedestal is provided. at itsmiddle with. an upstanding metal reinforcing post 14 which serves as areinforcing core :for the filling 12. r

In Figure 5 I have illustrated the construction of the curb at a corner,and, as shown, I provide a bar unit 2 having a vertical groove 6 at oneside thereof near one end of the bar, the opposite end of unit (5 beingconstructed like the units 2. Bar 6 is placed in position against theend of the bar 2 with its groove 6 registering with the groove 6 of bar2, and a key filling 12 is placed within the chamber provided by saidgrooves. The pedestal provided at such a corner may consist of a flatblock or plate of concrete or cement 15, having, like the pedestals 1, apost 14;.

What I claim is:

1. A sectional curb comprising a plurality of units each consisting of amolded bar of concrete or the like, said units being an ranged end toend; a plurality of pedestals for supporting said units consisting ofseparately molded blocks of concrete, each disposed below the abuttingends of two of said units, and means on each of said pedestals engagingthe opposite sides of both units operable to shift the ends of the unitslaterally to aline the same and serving also as means for holding saidends in position.

2. A curb comprising a plurality of units each consisting of a moldedbar of concrete or the like, said units being arranged end to end; aplurality of pedestals for supporting said units consisting of moldedblocks of concrete each disposed beneath the abutting ends of two ofsaid units; upstanding lugs at opposite sides of each pedestal; nutsembedded in said lugs, and screws mounted in said nuts and adapted toact against opposite sides of said units to aline and position saidunits laterally on said pedestal.

3. As a new article of manufacture, a ready made rail or bar unitconsisting of a molded block of concrete made with relatively shortsolid end sections connected by integral intermediate body portion of anangle-iron shape in cross-section comprising a horizontal top Wall and avertical side wall, the solid end sections serving, as elosures for theends of the groove or recess of the body portion and as reinforcementsfor the two walls of said body section.

el. As a new article of manufacture, a ready made pedestal unitconsisting of a molded block of concrete formed upon its top side with aseat adapted to receive upon it the abutting end portions of: two railunits, and adjustable means at each side of said pedestal adapted to beclamped against opposite sides of said rail units to aline the samerelatively and to position them laterally on said pedestal.

5. As a new article of manufacture, a ready made pedestal unitconsisting of a molded block of concrete formed upon its top side with aseat adapted to receive upon it and support the abutting end portions oftwo rail units, and screws udjustably mounted at opposite sides oi saidpedestal for alining and positioning the ends of. the rail units.

In testimony whereof I have ailixed my signature.
